A phenothiazine derivative of FCO‐CzS with changeable mechanoluminescence is reported, which, upon continuous mechanical stimulus, shows mechanoluminescent emission from blue to white and yellow. Careful analysis of the experimental results, coupled with the well‐understood photoluminescence theory, show that the molecular conformation transition of the phenothiazine group from quasi‐axial to quasi‐equatorial is responsible for this dynamic mechanoluminescence effect.

分子构象依赖性机械发光：相同的机械刺激但随时间变化的发射颜色

据报道，FCO-CzS的吩噻嗪衍生物具有可变的机械发光，在持续的机械刺激下，其显示出从蓝色到白色和黄色的机械发光发射。对实验结果的仔细分析，加上广为人知的光致发光理论，表明吩噻嗪基团从准轴到准赤道的分子构象转变是造成这种动态机械发光的原因。
